PROCESS FOR THE MANUFACTURE OF CURTAIN AND SIMILAR WOVEN STUFF Filed May 29, 1929 Patented June 21, 1932 UNITED STATES PATENT OFFICE JACOB VAN DEN BERGH, F NIJMEGEN, NETHERLANDS, ASSIGNOR TO NAAMLOOZE VENNOO'ISCHAP GEBRS. VAN DEN BERGHS INDUSTRIE EN HANDELMAAT- SCHAPPIJ', OF NORTH BRABANT, NETHERLANDS, A COMPANY OF THE NETHER- LANDS PROCESS FOR THE MANUFACTURE OF CURTAIN AND SIMILAR WOVEN STUFF Application filed May 29, 1929, Serial No.

The invention has for its object the manufacture of curtainand similar woven stuff, which is useful on both sides and therefore, hitherto had to be provided with a lining.

The process according to the invention enables one to manufacture a'texture, which on both sides possesses the desired condition, colour or pattern, so that the application of a lining can be saved.

The process consists in adding to the usual warps for the manufacture of the singular texture an auxiliary or third warp, which is a design warp forming with the weft threads a texture turned towards the reverse side and 5 entirely apart from the texture on the face side, the ground-Warp serving for both textures simultaneously.

In the accompanying drawing, Fig. 1 represents diagrammatically material forming the subject-matter of the present invention as produced in a single loom; and Fig. 2 a similar view of material produced in a double loom.

A simple form for the binding of such a tissue is illustrated in Figure 1, whereby on one side a plush and on the other side a smooth figured design is formed.

The pile-warp 10 forms with the weft threads 3, 5, 7 etc. and the groundwarpthreads 1 and 2 the plush for one side, whereas the weft threads 4, 6, 8 etc. form with the third warp f (the figure-warp) the figured side, so that on the tensioned warp 1 and binding warp 2 on both sides a texture of the desired condition, colour and pattern is formed.

The third warp f may be also a pile-warp, so that on both sides plush is obtained or inversely the pile-warp p may be a figurewarp, so that both sides are figured with the same or with a different pattern. All combinations, which in the art of Weaving by means of the choice of the materials, colours and patterns can be obtained, may be applied in this tissue on both sides.

366,989, and in Germany March 27, 1929.

It is not necessary to use the weft threads alternately for one texture and for the other, as is supposed in Figure 1. This method, however, is to be preferred, as in this manner the ground warp separates the two textures completely from each other and hence on one side nothing can be seen of the texture on the other side.

The application of other, eventually more complicated bindings remains in the process according to the invention completely free, whereas, as isillustrated in Figure 2, the invention can also be applied in a double loom.

For the same example, according to Figure 2, f and f are the two figure-warps (third warps), g and 9 the ground-warp for one texture and g and g, the ground-warp for the other texture. The pile-Warp p, which with the weft threads has to form the plushtexture for both textures, is cut through along the line m by the knife.

In manufacturing jacquard textures the effect can be obtained on both sides in each desired colour by means of the Welt.

What I claim is:

1. A woven fabric for curtains or similar hangings comprising a woven web formed of a single series of tensioned warp threads extending substantially straight therethrough, a single series of warp threads shedded alternately above and below said series of tensioned warp threads, weft threads inserted in the sheds formed by said two series ofwarp threads, design pile loops extending about all the weft threads on the same side of the tensioned warp threads to form a patterned surface, and a second series of design pile loops extending about all the weft threads on the other side of the tensioned Warp threads to form a like or different patterned surface, the pile loops and their engaging weft threads being on the same side of the tensioned warp threads respectively, whereby the patterned surface on each face is distinct from that on ghe other face and invisible from the other ace.

2. A woven fabric as claimed in claim 1 wherein the fabric is woven as a double web having the webs in superposed relation and the pile forming threads extend from the weft threads on the inner side of the tensioned warp threads in one web to the next adjacent weft threads on the inner side of the tensioned warp threads on the second web, said pile forming threads adapted to be cut to form separate webs.
